Answer the following questions from the information provided.

Paragon, a road construction company, must purchase a new paver to meet the growing demands for highway construction and resurfacing. The key parameters of the three pavers under scrutiny are provided below. Parameters A99 B88 C77 1. Initial Cost ($) 380,000 400,000 425,000 $290,000 at $300,000 at $310,000 from EOY1 increasing EOY1 EOY1 by $3,000 increasing by decreasing by 2. Revenues ($) annually 1% annually 3.0% annually thereafter thereafter. thereafter $125,000 at $175,000 at $185,000 at EOY1 EOY1 EOY1 3. Operating costs decreasing by decreasing by decreasing by ($) $1,000 annually 2% annually $2,500 annually thereafter. thereafter thereafter 4. End-of-life -6,000 45,000 30,000 salvage value ($) 5. Useful life (years) 3 years 4 years All parameter values are fictitious. EOY = End-of-year Industry Standard = 2.5 years MARR = 10% 6 years . 21. In this assignment, the conclusion of the Internal Rate of Return (IRR) method as to the best paver coincides with the conclusion of the Net Present Worth (NPW) method. A99's External Rate of Return (ERR). C77's External Rate of Return (ERR). 22. 23. 24. The incremental External Rate of Return (AERR) between pavers B88 and A99. 25. The incremental External Rate of Return (AERR) between pavers C77 and A99.
